21 Claims.

This invention relates to improvements in machines for operating upon the soles of shoes and is herein illustrated as embodied. in a rounding and channeling machine of the type disclosed in 5 United States Letters Patent No. 600,883, granted March 22, 1898, upon an application of W. C. Meyer and Z. T. French. The invention is set forth hereinafter with particular reference to the rounding and channeling of soles which have been 10 applied to shoes in the process of repairing the shoes. The invention is not necessarily limited, however, in its application to repair work nor to machines for performing both rounding and channeling operations." Neither is the invention lim- 15 ited to embodiment in machines of the particular type disclosed in the above-mentioned Letters Patent.

Machines of the type referred to 'are particularly designed for operation upon welt shoes and are not ordinarily adapted for operation upon the soles of McKay-sewed shoes or other shoes of the type wherein the tread sole is directly secured to the upper, although a rounding and channeling machine fitted with mechanism adapting it for op- 25 eration upon the soles of both welt and McKaysewed shoes is disclosed in United States Letters Patent No. 1,861,822, granted June 7, 1932, upon an application of O. L. Sherman and A. Bourgeois. 30' One object of the present invention is to provide, in a machine for operating upon the soles of shoes, further improvements adapting the machine for operation not only upon the soles of welt shoes, but also upon the soles of shoes of the type wherein no Welt or equivalent shoe bottom member is provided and wherein the tread sole is se cured directly to the upper, as, for example, in Mc- Kay-sewed shoes, turn shoes, and shoes wherein the outsole is attached partially or wholly by means of cement.

With this object in view, one feature of the invention consists in a machine for operating upon the soles of shoes of different types, comprising a movable feeding member or support for contact 45 with the work, a movable carrier, and a feeding device, belonging to a group of interchangeable feeding devices, arranged for mounting individually upon the carrier at the opposite side of a 1 sole from the movable member and co-operating 5 with said member to feed the work, said feeding device being arranged for operation upon a type of shoe different from those upon which other devices of the group are to operate. In the rounding and channeling machine herein illustrated 55 provision has been made whereby two work-feeding members or feed plates may be interchangeably attached to a feed plate carrier having the usual four-way feeding motion, thereby to adapt the machine for operation both upon the soles of welt shoes and upon the soles of McKay-sewed shoes. Each feed plate, when attached to its carrier, is adapted to enter the crease between the upper and the margin of the sole and to cooperate with a sole support intermittently to grip the sole margin and to impart step-by-step feed movements to the work. In resoling a welt shoe it is desirable to guide the shoe during the rounding and channeling of a new sole which has been temporarily secured to the shoe bottom by en' gagement with the edge of the welt which of 15 course has already been trimmed. To provide for the guiding of a welt shoe in this manner one of the interchangeable feed plates with which the present machine is provided has a welt edge gage rigidly secured thereto. In operating upon the outsole of a McKay-sewed shoe, however, there is no welt from which the shoe may be guided and, accordingly, the other feed plateused in the present machine is equipped with a gage arranged to engage the upper of the shoe along an area close to the sole margin to guide the shoe during the trimming and channeling of the outsole. To enable these two feed plates to be readily interchanged, clamping means is provided comprising a manually operable clamp bolt on the feed plate carrier and an open slot in the feed plate so constructed and arranged that by a simple manipulation of the clamp bolt one of the feed plates may be removed and the other attached to the feed plate holder, the parts being assembled with the end of the slot in the feed plate engaging the clamp bolt in such a manner as accurately to locate the feed plate in operative position in the machine.

In rounding and channeling machines as ordinarily constructed a work-supporting member, usually known as a crease guide, is provided for cooperating with the movable sole-feeding support to hold the work during those intervals when the feed plate has been retracted from feeding engagement with the sole margin. For a similar purpose the illustrated machine is provided with two normally stationary members, hereinafter more specifically referred to as presser feet, which are arranged for movement to different positions to adapt them to act with one or another of a group of feeding devices belonging to an interchangeable group, each designed for use with a particular type of shoe. As herein disclosed, the presser feet may enter the crease between the 5 upper and the sole margins at opposite sides of the feed plate, to engage the upper face of the welt, in a welt shoe, or the upper face of the outsole margin, in a McKay-sewed shoe, to assist in supporting the portion of the work being operated upon. The feed plate for welt shoes supports the work so that the upper face of the welt is located in a different vertical plane from that occupied by the upper surface of the margin of the outsole of a McKay-sewed shoe when such a shoe is supported by the other feed plate. To adapt the presser feet of the illustrated machine properly to assist in supporting and gripping the work, the presser feet are made adjustable between two positions in one of which they are located for engagement with the face of the welt of a welt shoe and in the other of which they are located in a different vertical plane for engagement with the margin of an outsole of a McKay-sewed shoe. The illustrated presser feet, for this purpose, are secured upon a pivoted carrier which is adapted to be moved about its pivot by a manually operable eccentric adjusting device between two positions in one of which the presser feet are adapted to bear against the upper face of the welt of a welt shoe and in the other of which they are adapted to bear against the upper face of the projecting outsole margin of a McKay shoe. The provision, in a rounding or a rounding and channeling machine, of a presser foot adjustable as and for the purpose described constitutes another feature of the present invention.

The invention further consists in features of construction and combinations and arrangements of parts hereinafter described and claimed, the

advantages of which will be apparent to those skilled in the art.

The invention will be explained with reference to the accompanying drawings, in which Fig. l is a view in front elevation. of so much of a rounding and channeling machine as is necessary to illustrate the application of the present invention thereto, the machine being shown as it appears when fitted and adjusted for operation upon a welt shoe, and certain parts of the machine being broken away for the purpose of better showing their construction;

Referring first to Figs. 1 and 3 of the drawings, the invention is therein shown as embodied in a rounding and channeling machine of the general type disclosed in Letters Patent No. 600,883, hereinbefore referred to, the machine being provided with a four-motion feed plate I4 adapted to enter the welt crease of a welt shoe and to have feeding engagement with the upper surface of the welt, a sole support comprising an anti-friction roller I6 which is movable back and forth to cooperate with the feed plate I 4 in feeding the Work; a vibratory rounding knife i8 which is movable toward the feed plate to trim the outsole of the shoe; and a channeling knife 25 which is secured to the sole support. The sole support, the rounding knife and the channeling knife, above referred to, are substantially the same in construction and have substantially the same mode of operation as corresponding parts disclosed in said patent and, accordingly, no further description of these parts will be given herein. The machine is shown in Fig. 3 as operating to trim and form a stitch-receiving channel in a block outsole A which has been applied to a welt shoe, comprising an upper B and a welt C, in the process of repairing the shoe and temporarily secured to the shoe bottom by cement.

As best shown in Figs. 7, 8 and 9, the illustrated feed plate I4 is made in two parts consisting of an active portion 22, hereinafter referred to as the feed point, and a block or holder 24 to which the feed point 22 is fixedly secured. To adapt the illustrated machine for operation upon the soles of welt shoes, the feed point 22 has fixedly secured to its rear side a gage plate or welt edge gage 26 having a lower edge face 28 which is located above the lower extrernity of the feed point 22 and is adapted for guiding a shoe by engagement with the previously trimmed edge of the welt. The edge 28 of the welt gage 26 is formed upon a block 30 of soft metal, which is dovetailed into the lower portion of the gage plate 25 to furnish a surface with which the rounding knife l8 cooperates in trimming a sole. The lower portion of the feed point holder 24 is notched or cut away, as indicated at 32 (Fig. 9), to receive the feed point 22 and the latter is positively located within the cut-away portion by means of two dowels 34, 34, which extend from the feed point holder into holes in the feed point. The welt gage 2B is secured to the feed point 22, and the feed point is secured to the holder or block 24, by means of a screw 36 the head of which is seated within the counterbored portion 38 of a recess in the holder and the shank of which extends through an aperture 40 in the feed point and is threaded into a clamp plate 42 which fits within a vertical slot 44 in the welt edge gage 26. A dowel 45 in the clamp plate 42 extends into one of the beforementioned dowel holes in the feed point 22 to assist in holding the clamp plate in place. The opposite lateral edges of the clamp plate 42 are beveled, as shown at 46 in Fig. 8, to overlie the corresponding beveled lateral edges of the slot 44 in the welt gage, the slot 44 being longer than the clamp plate 42. Consequently by loosening the screw 36 the welt gage 28 may be adjusted up or down relatively to the feed point to accommodate shoes having welts of different widths. The feed point holder or block 24 is, in turn, fixedly secured to a feed plate carrier 48 (Fig. 1) mounted for oscillatory and also lateral.

sliding movements upon a rod or bar 50 which is fixed at its opposite ends within frame members 52. The feed plate carrier 48 is caused to oscillate and to slide laterally upon the rod 50 to impart a four-way feeding motion to the feed point 22 by means of cam mechanism which is not herein shown but which may be of the same construction as that of corresponding mechanism disclosed in Letters Patent No. 600,883 already referred to.

To adapt the machine for operation upon the soles of shoes in which no welt is employed, such for example as the McKay-sewed shoe D (Fig. 6) having the block outsole E applied thereto, a

7 second feed plate 56 is provided (see Figs. 6, l

and 11). The feed plate 56 comprises a feed point 58 and a feed point block or holder 61! to which the feed point is rigidly secured, and a gage 62 is associated with the feed point 58 for guiding a shoe by engagement with the shoe upper. As shown, the feed point holder 60 is identical in construction with the feed point holder 24 hereinbefore described, in order that the same pattern may be employed in the manufacture of both holders, thereby reducing the cost.

The two feed points 22 and 58 may be used interchangeably in it to adapt the machine for operating upon both welt shoes and McKaysewed shoes. For this purpose, each of the two feed point blocks or holders 24 and lib is provided in its upper portion with a vertical slot 54 which is open at its upper end to receive a clamp screw 6'5 on the feed plate carrier 48. In order to provide for the manual operation of the screw 66 in a manner to permit instant removal or attachment of either feed plate, said screw is threaded within the feed plate carrier it! and has fixedly secured to one end a handle it shaped to be conveniently grasped by the operator and by which the screw may be turned to cause the feed plate holder to be clamped between the head 12 and the side of the carrier A8. The pitch of the threads on the screw is preferably such that less than a full turn will be suflicient to clamp or unclamp the feed plate. Each feed point holder is adapted to be located vertically in proper relation to the cooperating elements by engagement of the lower end of the slot G with the shank of the screw 66. A vertically elongated tongue or rib 'M on the carrier t8 extends into the slot 64 and into a groove '56 which constitutes an extension of the slot 64 at one side of the feed point holder to hold the latter firmly against angular displacement.

Referring now specifically to the feed plate 56, the gage $2 is located relatively to the feed point 58 to engage the upper of a shoe in a locality closely adjacent to the sole edge. It comprises a small roll having a periphery which is slightly concave transversely to conform substantially to the contour of the shoe upper at that point, as shown in Fig. 5. The gage roll 62 is mounted upon the lower end of an arm 18 the upper portion of which is fitted within a shallow groove 80 in the feed point holder 6i}, the arm 18 being bent, as shown in Fig. 11, to support the roller in close proximity to the feed point. The arm 18 is rigidly secured to the feed point holder 69 by a screw 82 the shank of which extends through a vertical slot as in the arm 13, through a hole 85 in the feed point holder fill, and is threaded into the feed point 58. As hereinbefore pointed out the construction of the feed point holder 6% is the same as that of the holder 24 and, in order to provide for the firm clamping in place of the arm 78, the counterbored portion of the hole 85 (which corresponds to the counterbore 38 in the holder 24) is filled by means of a collar 86. As shown, the gage arm 18 is firmly held in place between the collar 86 and the head 83 of the screw 82 and edgewise displacement of the gage arm 18 is prevented by the sides of the groove 80. Angular displacement of the feed point 58 relatively to its holder Bil is prevented by means of dowels til, 9i! which extend from the feed point into the feed point holder. As shown, a cutting block 92 of soft metal is inserted in the lower portion of the feed point 58 for cooperation with the rounding knife i8.

In order that the cutting block $2 shall cooperate with the rounding knife E8 the feed point 58 is made thicker than the feed point 22, the thickness of the feed point 58 being equal to the combine-d thickness of the feed point 22 and the welt edge gage 25. Therefore when the feed point 555 is being used in the machine, the face of the cutting block 92 will be located in the same vertical plane as that occupied by the face of the cutting block 36 when the feedpoint 22 has been applied to the machine.

For the purpose of properly supporting the margin of a sole during those intervals when the four-motion feed point is retracted from feeding engagement with the sole, the present machine is provided with two stationary work supporting members or pre-sser feet as which are located one in front of and the other beyond the feed point so as to insure that the sole margin shall be adequately supported during the operating movement of the channeling knife. 55 are shaped, as shown in Figs. 1, 3, 4 and 6, to enter the welt crease of a welt shoe (or the corresponding crease between the upper and the outsole of a McKay-sewed shoe), being formed for this purpose with beveled lower extremities adapting them to extend substantially to the bottom of the crease and thus most effectively to support the sole margin. As shown, the angle of bevel of the work-engaging portions of the presser feet is somewhat steeper than that of the corresponding portion of the feed point. As a result of this, they have no tendency to limit the extent of projection of the feed point into the crease and thus in no way to interfere with the effective feeding engagement of the feed point with the work. The presse-r feet are located close to the feed point, they being separated by only sufficient space to provide-the necessary clearance for its backward and forward movement. As illustrated, the presser feet 9'3, 96 are fixedly secured by means of screws 98, 98 to a carrier arm Edi) (best shown in Fig. l) which, in turn, is mounted upon a bracket 552. The bracket N32 is conveniently hung upon the rod 5 3 and is formed with a rearwardly extending arm which is rigidly secured by means of a bolt ass to one of the frame members 52. The bolt extends through a hole IE8 in the frame member which is somewhat larger than the diameter of said bolt so that ample provision is made for a forward or backward setting-up adjustment of the presser feet in order that they may be econrately brought into the desired cooperative relation to the feed point. The screws 28, 93 extend through vertical slots HE Ms (Fig. l) in the upper portions of the presser feet to permit upand-down adjustment of the latter relatively to the carrier 5% so that the presser feet may be accurately positioned relatively to each other and to the feed point.

It is desirable that the work-engaging surfaces of the two presser feet shall bear the same relation to the work-engaging faces of the feed point whether the feed point 22 is employed toadapt the machine for operation upon welt work or the The presser feet feed point 58 for operation upon McKay work. Accordingly, provision is made for adjustment of the presser feet into two positions in one of which the presser feet will be adapted to support the sole margin of a welt shoe by engagement with the upper surface of the welt and in the other to engage the upper marginal surface of the projecting outscle of a McKay shoe. To this end, the carrier arm I80 to which the presser feet are secured is pivotally mounted in the bracket I02, as indicated at H2, and a rearward extension H of the carrier arms I00 is slotted, as shown at HE (Fig. 4), to receive an eccentric portion HS of an adjusting stud I29 rotatably mounted in the bracket arm 64. The stud is provided with a knurled collar I22 by which it may be turned to shift the presser feet between the positions shown in full and dotted lines. The presser feet are thus located in positions to engage, respectively, the upper face of a welt of a welt shoe and the upper surface of the margin of the outsole of a McKay shoe. The above-mentioned two positions of the presser feet are positively determined by the engagement of a springpresscd detent I24 carried by the arm I84 with one or the other of two notches I26, 28 in the adjusting stud I23. As shown, the detent H24 is shaped so that it will readily yield to release the adjusting stud I28 when the latter is turned but will nevertheless securely hold the stud in either of its two adjusted positions.

In using the illustrated machine for operating upon the soles of welt shoes the feed plate 24 with the welt gage 26 are employed and the presser feet 96 are adjusted into the position shown in Fig. 3 and in full lines in Fig. 4. In using the machine for operating upon the soles of McKay shoes, or other shoes in which no welts are provided, the feed plate 56 with the upper gage 82 are employed and the presser feet 96 are adjusted into the position shown in Fig. 6 and in dotted lines in Fig. 4. The feed plates are instantly interchangeable upon manipulation of the clamp screw l0 and adjustment of the presser feet is readily effected by a partial turn of the knob I22. The construction and mounting of the feed plates and of the presser feet are such that those parts are accurately positioned and rigidly supported at all times.
